VALVE-CAGE FOR PUMPING-ENGINES.

SPECIFICATION forming part of Letters Patent No. 769,707, dated September 13, 1904.

Application filed June 20, 1904.

in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Valve-Cages for Pumping-Engines,

of which the following is a specification.

My invention relates to pumps especially adapted for use with pumping-engines, and particularly relates to the valve mechanism, the removable valve support or cage, and means for securing same in position and removing it therefrom. It is customary in devices for this purpose to employ a great number of comparatively small valves.

The object of my invention is to provide a suitable removable support for said valves whereby they may be readily removed for cleaning and repairs, and, further, to provide suitable bearings for said support whereby it will be properly seated and held in relation to other parts of the apparatus and will be enabled to withstand the great strain incident to the passage of a volume of water through said valves.

' With the above primary and other incidental objects in view the invention consists of the constructions and combinations of parts hereinafter described, and set forth in the claims.

In the drawings, Figure l is a vertical sectional View of the pumping apparatus. Fig. 2 is a horizontal sectional view of the intake member and valves. Fig. 3 is a perspective view of the cage for the support of the valves. Fig. 4 is adetail of the valves. Fig. 5 is a sectional View of a modified form.

Like parts are represented by similar characters of reference throughout the several views.

In said drawings, (4 represents the intake member; a, the incoming main discharging into said chamber; cf, the outlet-chamber, and a the outgoing main. Located between the two said chambers a and c but having connection with both by a series of valves, is the plunger-chamber b. The plunger 6, located therein, is given a vertical reciprocating movement by any suitable means and by displacement causes the movement of the water. In

Serial No. 213,24?! (No model.)

order that the flow may be uniform, each of the chambers a a is provided with the usual dome a (0 The series of valves between the chamber a and the intake and outlet chambers are mounted in cages. The general form of this cage is tapering or slightly conical, as shown in Fig. 3, and is provided with circular heads 0 0, which fit openings in opposite sides of the in take and outlet chambers. The portion of the cage between the heads 0 0 is preferably rectangular in section and open on one side, the remaining three sides being provided with openings 0 for the reception of the valves. The edges of said open side of the cage are provided with lips 0* a, which register with the edges of the dividing-walls c 0 between the plunger-chamber b and the chambers on either side thereof. In order to strengthen said rectangular portion of the cage, it is divided into a plurality of compartments by a series of vertical partitions c and a central longitudinal partition 0 As a further security against breakage by the impact of the water and to prevent the flanged part of the cage catching on the openings in the webplates when inserting the cage and upon the withdrawal of the same from the chamber external longitudinal ribs are provided upon three sides of the cage. These ribs d extend vertically to the sides of said rectangular portion of the cage and extend from the head 0 to the head 0. A plurality of external transverse circular ribs or diaphragms d are also provided, which extend around the rectangular portion of the cage between the heads a c.

Arranged between the walls of the chambers a a is a plurality of vertical webs 6, equal in number to the circular ribs d. Each of the vertical webs a has a circular opening whose diameter is equal to that of the corresponding circular rib d. The vertical webs are so located that when the valve-cage is seated in its proper position each of the circular ribs d will register with the corresponding vertical web 6, and thussupport the central portion of the valve-cage. In the drawings the valve-cage has been shown divided into eighteen compartments, each compartment having six valve-openings therein.

However, these proportions may be varied without departing from the spirit of the invention.

In Fig. a is shown a detail of the valve,which consists of the valve-seat f, which is screwed or otherwise secured in the openings 0 of the cage. 7" is the valve longitudinally movable on the stern f against the tension of the springf The parts are held in position by the flanged collar f and nut f Referring to Fig. 2, g is the cover for the opening through which the valve-cage is inserted. This cover gis provided with a central screw-threaded opening through which extends a screw 9. After the valve-cage is placed in position the cover is secured in position, and by operating the screw g, which bears on the head 0, the valve-cage is properly seated and securedin position, the openings in the chamberand vertical webs e having been bored to a taper corresponding to that of the exterior of the valve-cage heads and ribs. A cap-nut g covers the extremity of the screw 9 and serves as a lock-nut after the cage has been properly adjusted. A cover 9 similar to the cover g, is provided for the opening in the opposite side of the chamber, and a screw 9 extends through this cover g and has bearing on the head 0 of the valvecage. This screw 9' is of great service in starting the valve-cage from its seat when it becomes necessary to remove it for cleaning or repairs. In order that the pressure on both sides of the heads 0 0 may be equal, holes h are provided which will admit sufficient Water to fill the chamber between the heads 0 0 and the covers g and g respectively.

WVhile the central portion of the cage is preferably formed rectangular in section, as has been described, it may be modified into a polygon with numerous sides, as shown in Fig. 5, where it is shown as a polygon withv sixteen sides and having the vertical partitionsa'and the longitudinal central partitions y, corresponding to the partitions 0 0 of the preferred form.

In Fig. 5 are further shown the external longitudinal ribs 02 and circular ribs m corresponding to the ribs (Z and cl. In addition to these there are shown a series of internal longitudinal ribs 2,extending radially between the respective valve-openings.

It is obvious that I thus provide a construction wherein the valve-cage will be easily seated and removed therefrom and a cage structure reinforced in such manner by the ribs, partitions, and vertical webs as to successfully withstand the great strains to which it will be subjected. It will also be observed that by forming the valve-cage tapered, as described, and boring the openings in the sides of the chamber and webs e to a corresponding taper the cage will be given a perfectly tight fit and will be held firmly in position without other means of fastening.

Having thus described my invention, I claim 1. In a structure as described, a valve-cage having a general conical form, circular heads adapted to fit openings in opposite sides of the waterchamber, circular ribs on said valvecage and intermediate of said heads, and supporting-webs with which said circular ribs are adapted to register, substantially as and for the purpose specified.

2. In a structure as described, a valve-cage divided into a plurality of compartments, circular heads and external longitudinal and transverse ribs, the whole forming a body of slightly conical shape, substantially as and for the purpose specified.

3. In a structure as described, a chamber, circular openings in opposite sides thereof, and intermediate webs having circular openings therein in alinement with said first-named openings, :1. valve-cage having circular heads and intermediate circular ribs adapted to register with the openings in said chamber sides and webs respectively, substantially as specified.

4C. In a structure as described, a valve-cage having circular ends, an intermediate portion of smaller diameter than said ends, external longitudinal ribs and transverse circular ribs on said intermediate portion, the outer edges of said external ribs being in alinement with the periphery of said circular ends, substantially as specified.

5. In a structure as described, a waterchamber having openings in the opposite sides thereof, a valve-cage adapted to fit into said openings, means to support said valve-cage intermediate of its ends, covers for said chamber-openings, and screws extending through said covers and bearing on said valve-cage, substantially as and for the purpose specified.

6. In a structure as described, a waterchamber, a valve-cage mounted therein, members attached to said water-chamber walls and extending over the ends of said cage, screws carried by said members and bearing on the ends of said cage, whereby said cage may be seated and secured by the operation of one of said screws and unseated by the operation of the opposite screw, substantially as and for the purpose specified.

7. In a structure as described, a waterchamber having openings in the opposite sides thereof, a valve-cage having circular heads adapted to fit into said openings, a reduced intermediate portion divided into a plurality of chambers, external longitudinal and transverse ribs on said reduced portion which cooperate with said heads to give to said cage a general conical form, and means to support said cage intermediate of its ends, substantially as specified.

8. In a structure as described, avalve-cage consisting of circular heads, an intermediate valve-chamber of reduced diameter divided into a plurality of compartments, external longitudinal and transverse ribs, and means including two screws for seating and unseating said valve-cage, substantially as specified.

9. In a structure as described, a waterchamber, a valve-cage therein of a conical form, screws adapted to exert pressure on the respective ends of said cage, bearings for said screws independent of said cage, whereby saidcage may be seated and unseated by the operation of said screws, substantially as specified.
